If it's not locked, simply move your mouse cursor to a blank area, press and hold your left mouse button, move the panel to your desired location, and release the left mouse button. If it is locked, right-click on the panel and left-click on Lock Panel (which will remove the check mark) before attempting to move it.

Or you can create an additional panel on the top (et cetera) if you would rather have one in each location. Some people do this, placing different panel applets on each.
